Note that you really do want ppp 2.4.5 since you're getting the bogus nameserver problem (which NM covers up by using 4.2.2.x instead). See the link to the fixed packages in that bug, or you can simply: yum update NetworkManager ppp to get the fixed packages now that they are in F12-updates. *** This bug has been marked as a duplicate of bug 548520 *** |
Created attachment 396701 [details] System dmesg output Description of problem: Prior to recent sequence of patching F12, NetworkManager connected successfully to AT&T network. Unsure which, but current kernel/NetworManager components result in no connection. Hardware: AT&T Sierra 875 PC-Card IBM/Lenovo Thinkpad T60 Version-Release number of selected component (if applicable): kernel-2.6.31.12-174.2.3.fc12.x86_64( and newer) NetworkManager-0.7.997-2.git20091214.fc12.x86_64 How reproducible: Tested using 3 most recent kernels - no change Steps to Reproduce: 1. Insert Aircard 2. Click previously defined AT&T Broadband MediaNet 3. Monitor NetworkManager in panel 4.
